[issue30427] isinstance checks in os.path.normcase redundant with os.fspath

[Brett Cannon]

Brett Cannon added the comment:

The problem with leaving os.fspath() out of os.path.normcase() is that suddenly a single function that deals with paths won't work with path-like objects. So that means support for path-like objects won't implicitly work in code that assumes a path but doesn't explicitly go out of its way to support path-like objects.
